This is a simple experiment you can do at home. Take three pieces of white cardboard - business cards are perfect. Cut a very narrow slit in the first piece of cardboard. Cut two very narrow slits - about a half inch apart - in the second piece of cardboard. NOTE: The slits only need to be an inch or two long. It is really important to make very narrow slits - as narrow as your scissors will allow. Make sure the slits are evenly cut, so that they are the same narrow width thoughout the length of each slit. Also, make sure the slits on the second card are parallel. Set up a lamp on a flat desk or table with a bare light bulb so that the light bulb is about two or three feet above the table. Hold the first piece of cardboard (with one slit) very close to a light bulb. Do not let it touch the light bulb to avoid risk of fire. Now hold the second piece about two feet below the first card, so that the light that passed through the slit on the first card falls around both slits of the second cardboard. Now place the third piece of cardboard (with not slits) on a table below the cardboard with two slits. All three pieces of cardboard should be lined up so that the light passes first through the cardboard with one slit, and then through the cardboard with two slits, and then onto the cardboard with no slits. Observe the light striking the third piece of cardboard. You will see many bands of lighter and darker areas. If you do not see it right away, move the cardboard with two slits up and down slowly to adjust the focus on the third card. These bands of alternating bright and dark zones are called interference patterns, and are a function of wave interaction. Waves of light pass through the slits of the second piece of cardboard (the one with two slits), and the waves from the two slits combine to make the light brighter at some points (constructive interference), or cancel to make the light darker at other points (destructive interference), thus creating the interference pattern. You can create the same interference pattern on a perfectly smooth pond, puddle, or bath tub by dropping in two small pebbles about two or three feet apart simultaneously. As you watch the ripples radiate outward from the two impact points, the waves will combine in some points to make even higher waves, and will cancel each other out in other points.
The light wave is electromagnetic yes.
The type of electromagnetic wave the borders visible light at the red end of its range is the Infrared light wave.
The polarization of light is best supported by the wave model of light, which describes light as an electromagnetic wave with oscillating electric and magnetic fields perpendicular to the direction of propagation. In the wave model, polarization occurs when the electric field oscillates in a specific orientation, leading to light waves that are aligned in a particular way. This model explains how polarizing filters can selectively block certain orientations of light waves, demonstrating the wave-like nature of light.
Light behaves as both a wave and a particle in chemistry. As a wave, light exhibits properties such as interference and diffraction, while as a particle, light consists of discrete packets of energy called photons. This dual nature of light is described by the wave-particle duality principle.
Electromagnetic radiation, such as visible light or gamma rays, travels at the speed of light, which is approximately 300,000 kilometers per second in a vacuum. This energy is characterized by its wave-like behavior and carries energy in the form of photons.
Light is actually a transverse wave, not a longitudinal wave. This is evidenced by the fact that light waves oscillate perpendicular to the direction of their propagation. Longitudinal waves, on the other hand, oscillate parallel to the direction of their propagation.
One characteristic that proves light is a transverse wave is that it oscillates perpendicular to the direction of its propagation. This means that the electric and magnetic fields of light waves are oriented perpendicular to the direction it travels. Additionally, light waves exhibit properties like polarization and interference, which are characteristic of transverse waves.
Photoelectric effect is where electrons are emitted from a material when it is exposed to light. This phenomenon proves that light can behave as both a wave and a particle (photon). It is a key concept in understanding the interaction of light with matter.
Light is an example of a electromagnetic wave.
A sonic wave.
I would rather say that light IS a wave, not that it HAS a wave. It is a type of electromagnetic wave.
No, light is a transverse wave.No, light is a transverse wave.No, light is a transverse wave.No, light is a transverse wave.

Light is an electromagnetic wave.
The light wave is electromagnetic yes.
Yes, light is an electromagnetic wave.
The concept of light as a particle originates from the wave-particle duality principle in quantum mechanics. Experimental evidence, such as the photoelectric effect and the double-slit experiment, supports the idea that light exhibits both particle-like and wave-like properties.
